when i got this car, the valence was not attached, and it was pretty well cracked up. on one corner there was a spider crack with a quarter sized hole missing, the other side the bottom visible inch was gone for about 5 inches long at the corner.
First i sanded and washed everywhere around the damaged area.
I bolted everything i could together with metal plates, making sure none of the screws would show.
Then I super glued all the cracks together as a temporary fix to hold it together while i worked
Then i used bendable metal tape (think aluminum foil) and superglued it where the missing parts of the valence would be.
I wrapped this with about 4 layers of fiberglass, letting it dry and sanding after each time. I did not quite go as far out as the missing part did, but very very close.
I then coated the whole vicinity in bondo, scraping off any excess.
Sanded off the bondo, and in to the urethane in some places, making it completely flat.
At this point, it is sanded finished, but still needs to be painted. I took it and yanked the hell out of it, to the point i doubt the original urethane would hold up (no reason to bolt it up if it is not strong) Looks good. I will sand the whole valence tommorow in prep for painting.
I'm sorry i dont have any pics. Oh, and this is my first body work, so if i should have done something, pipe up!
